A mass of radioactive polluted water that arisen from the Accident at Fukushima Nuclear Power Stations is just stored on the sites. We presume the polluted water contains sodium chloride and boric acid; therefore, developments of new immobilization matrices suitable for these chemicals are required. In this study, it was focused attention on borate glass based immobilization with the use of boric acid in the polluted water. In our previous work, it was confirmed that a borate glass is formed when boric acid and sodium chloride powder were used in a molar ratio 1:0.5 and they were melted at 1100
C for three hours. A borate glass will be formed if chlorine is volatilized from the glass. In this time, we studied on thermal behaviors during forming a glass to make sure that chlorine is volatilized from the glass.

Platinum nanoparticle catalysts for fuel cell applications were prepared by ion implantation in a glassy carbon substrate followed by electrochemical etching and thermal treatment. Interestingly, they had a strong interaction with the substrate via platinum-carbon bonds, probably thereby achieving high catalytic activity for the oxygen reduction reaction.
